Checksum correction CWs

[fire19740]

Hi,
is it possible to disable the checksum correction CWs at the cccam protocol? Or build a switch.
I know this is not DVB-standard - but some providers ignores standards to block other receivers and to sell their own hardware.

e.g. on OSCAM Servers the switches are
for the whole card in reader:
disablecrccws =1
for the some providers:
disablecrccws_only_for = 098C:000000;09C4:000000

thx
